LM10: Refinement Revisited

The Queue Machine

The Queue Machine

presentation slides used in the presentation (actually an updated version) 238 slides
notes the slides reduced to note form, even more suitable for printing 34 pages
lectopia an innovative first: the lectopia recording of this lecture (although the audio is not very good)

Refinements as a lattice: a series of refinements to a full specification

Corrections to the published slides

I have noticed a number of typos in the published slides. As I don't have the source to correct these slides, I'm reproducing the list here (numbers refer to slide numbers):

181
    qnext & id(ITEM) = {}
should read
    qnext /\ id(ITEM) = {}
(and also in the closure below) The ASCII representation for intersection is a little too like the conjunction operator!
204
Note the broken right override operator
206
The right override operator should be replaced by domain subtraction (in both instances).
207, 209, 210, 211
The right override operator should be replaced by domain subtraction.
212
broken range subtraction operator
214
The right override operator should be replaced by domain subtraction.
